Step-by-step explanation:

The solutions for the given problems involving factorials and permutations are 8! = 40,320, 5P5 = 120, 8P4 = 1,680, 7P7 = 5,040 and the number of arrangement for 4 performers out of 9 is 3,024.

The subject here is mathematics, specifically factorials and permutations. Factorials are represented by the symbol '!'. The factorial of a number n is the product of all positive integers less than or equal to n. For example, 8! = 8*7*6*5*4*3*2*1 = 40,320.

Permutations refer to the number of ways a set of objects can be arranged. 'nPn' always equals to the factorial of n, therefore 5P5 equals to 5! = 5*4*3*2*1 = 120 and 7P7 equals to 7! = 7*6*5*4*3*2*1 = 5,040.

'nPm' equals to n factorial divided by (n-m) factorial. So, 8P4 equals to 8!/(8-4)! = (8*7*6*5)/1 = 1,680.

For the last question, the number of ways 4 performers can stand in a row out of 9, is calculated as a permutation of '9P4' (because the order of performers matters). Thus, it will be 9!/(9-4)! = 9*8*7*6 = 3,024.

Answer:

the cylinder container has the greatest surface area.

Step-by-step explanation:

The volume of cone is calculated by [tex]v=\frac{1}{3}\times\pi\times r^{2}\times h[/tex]

The volume of cylinder is calculated by [tex]v=\pi\times r^{2}\times h[/tex]

The volume of square pyramid is calculated by [tex]v=\pi\times r^{2}\times h[/tex]

The volume of rectangular prism is calculated by [tex]v=\frac{1}{3}\times B\times h[/tex]

The radius of cone is [tex]\frac{6}{3}[/tex]=[tex]2in[/tex], and slant height is 10 in.

height is calculated as h² = l²- r²

h² = l²- r²

h² = 10²- 3²

h² = 100- 9

h² =91

h= 9.54

The volume of cone is  [tex]=\frac{1}{3}\times 3.14\times 3^{2}\times 9.54[/tex]

[tex]=\frac{1}{3}\times 3.14\times 9\times 9.54[/tex]

v=89.8668

The volume of cylinder is [tex]=3.14\times 3^{2}\times 10[/tex]

[tex]=3.14\times9\times 10[/tex]

v=282.6

The volume of square pyramid

The height of pyramid is calculated as h² = l²- r²

h² = 10²- 3²

h² = 100- 9

h² =91

h= 9.54

[tex]v=3.14\times 3^{2}\times 9.54[/tex]

[tex]v=3.14\times 9\times 9.54[/tex]

[tex]v=269.60[/tex]

The volume of rectangular prism[tex]v=\frac{1}{3}\times 6\times 10[/tex]

[tex]v=20[/tex]

Hence, the cylinder container has the greatest surface area.

Answer: 2.35 square miles.

Step-by-step explanation:

To solve this exercise you must apply the formula for calculte the area of a sector in a circle, which is shown below:

[tex]A=r^2\pi(\frac{C}{360})[/tex]

Where C is the central angle in degrees and r is the radius.

Therefore, knowing that:

[tex]C=30\°\\r=\frac{6mi}{2}=3mi[/tex]

When you substitute values, you obtain the following result:

[tex]A=(3mi)^2\pi(\frac{30\°}{360})[/tex]

[tex]A=2.35mi^2[/tex]

Answer:

Area of sector = 2.355 miles²

Step-by-step explanation:

Formula:

Area of circle = πr²

Where r is the radius

Area of sector = πr²(C/360)

Where C is the angle of sector

It is given that radius of circle is 6 miles

To find the are of circle

Here diameter = 6 miles,

radius r = diameter/2 = 3 miles

Area = πr² = 3.14 * 3² = 28.26 miles²

To find area of sector

Here r = 3 and C = 30°

Area of sector = πr²(C/360) = 28.26*(30/360)

= 2.355 miles²

The inequality -6n < -12 has all numbers greater than 2 as its solution after isolating 'n'. We achieve this by dividing both sides by -6 and flipping the inequality sign.

To solve this inequality, -6n < -12, you first need to isolate 'n' on one side of the inequality. We do this by dividing both sides of the inequality by -6. It's important to remember that when we divide or multiply an inequality by a negative number, we need to flip the direction of the inequality sign. So, the inequality would become n > 2. This means that all numbers greater than 2 are the solutions of the inequality.

Answer:

The area of the picnic table is [tex]18.75\ ft^{2}[/tex] or [tex]18\frac{3}{4}\ ft^{2}[/tex]

Step-by-step explanation:

we know that

[tex]1\ yd= 3\ ft[/tex]

Let

L-----> the length of the table

W----> the width of the table

the area of the table is

[tex]A=LW[/tex]

Convert yards to feet

[tex]L=\frac{5}{6}\ yd=\frac{5}{6}*3=\frac{5}{2}\ ft[/tex]

[tex]W=3L[/tex]

[tex]W=3(\frac{5}{2})=\frac{15}{2}\ ft[/tex]

substitute in the formula

[tex]A=\frac{5}{2}(\frac{15}{2})=\frac{75}{4}=18.75\ ft^{2}[/tex]

To calculate the area of the picnic table, convert the length to feet and multiply by the width, also in feet, to find the area in square feet.

The student is asking about the area of a picnic table in square feet when the width is 3 times the length and the length is given as 5/6 yard. To find the area, first, calculate the width by multiplying the length of 5/6 yard by 3, which gives 5/2 yards (or 2.5 yards).

Since there are 3 feet in a yard, we convert the measurements to feet: 5/6 yard is equal to 5/6 * 3 feet, and the width is 2.5 * 3 feet. Next, multiply the length and width in feet to find the area.

It is important to note that converting measurements should retain unit consistency throughout the calculation.

Answer:

Option F. [tex]200.96\ ft[/tex]

Step-by-step explanation:

we know that

The circumference of a circle is equal to

[tex]C=\pi D[/tex]

in this problem

[tex]D=64\ ft[/tex]

substitute

[tex]C=\pi (64)=64\pi\ ft[/tex] -----> exact value of the circumference

Find the approximate value of the circumference

assume

[tex]\pi=3.14[/tex]

[tex]64\pi\ ft=64(3.14)=200.96\ ft[/tex]

The correct answer is option F. The measurement is closest to the circumference of the base of the observatory is 200.96 ft.

To find the circumference of the base of the observatory, we use the formula for the circumference of a circle, which is [tex]\( C = \pi \times d \)[/tex], where [tex]\( C \)[/tex] is the circumference and [tex]\( d \)[/tex] is the diameter of the circle.

Given that the diameter of the floor of the observatory is 64 feet, we can plug this value into the formula:

[tex]\( C = \pi \times 64 \) feet[/tex]

Using the approximation [tex]\( \pi \approx 3.14159 \)[/tex], we calculate the circumference as follows:

[tex]\( C \approx 3.14159 \times 64 \)[/tex] feet,

[tex]\( C \approx 200.96 \)[/tex] feet.

The complete question is:

An observatory is shaped like a cylinder standing on one of its bases with a dome on top. The diameter of the floor of the observatory is 64 feet, as shown in the diagram.

Which measurement is closest to the circumference of the base of the observatory in feet?

F 200.96 ft

G 3,215.36 ft

H 100.48 ft

J 401.92 ft

Answer:

sqrt(50)

Step-by-step explanation:

Since it is a right triangle, we can apply the Pythagorem Theorem.

a^2 + b^2 = c^2

25 + 25 = c^2

50 = c^2

c = sqrt(50)

The length of the diagonal of the square is 5 [tex]\sqrt{2[/tex]

The length of the diagonal of a square is equal to the square root of 2 times the length of a side. In this case, the side length is 5, so the diagonal of the square is 5√2

Let's break down the steps to find the square root of 50:

1. **Given**: We have a right triangle with side lengths:

 [tex]- \(a = 25\)\\ - \(b = 25\)2. Apply the Pythagorean Theorem: \[a^2 + b^2 = c^2\] \[25^2 + 25^2 = c^2\] \[50 = c^2\]3. Solve for \(c\): \[c = \sqrt{50}\]4. Calculate the square root of 50: \[c \approx 7.07\][/tex]

Therefore, the length of the hypotenuse (\(c\)) in this right triangle is approximately 7.07 units

The volume of a rectangular prism is equal to

[tex]V=LWH[/tex]

we have

[tex]L=3\frac{1}{2}\ ft=\frac{3*2+1}{2}=\frac{7}{2}\ ft[/tex]

[tex]W=3\frac{1}{2}\ ft=\frac{3*2+1}{2}=\frac{7}{2}\ ft[/tex]

[tex]H=8\ ft[/tex]

substitute in the formula

[tex]V=(\frac{7}{2})(\frac{7}{2})(8)=98\ ft^{3}[/tex]

Part b) If they are only going to fill the dunking booth 6/7 full, how many cubic feet of water will they need?

Switching the sides of the equation we get:

[tex] c \times 7 = -5 [/tex]

Then dividing both sides of the equation by 7 to get:

[tex] c = - \frac { 5 } { 7 } [/tex]

Answer:

150

Step-by-step explanation:

500 is 125% of 400 (500/400) so you need to get what 125% of 120 is

120                              x   1.25                            =150

^number of children        ^125% as a decimal

To find the number of children after the same percent increase in population as the adults, calculate a 25% increase based on the adult growth from 400 to 500. Applying this to the original child population (120), there were 150 children in 2010.

The question pertains to the percent increase in population and requires finding the number of children in a town given the increase in adult population. Specifically, the child population in 2000 was 120, and the adult population increased from 400 to 500 from 2000 to 2010. Assuming that the child population increased by the same percent as the adult population, we need to calculate this percentage increase and then apply it to the number of children to find the updated child population in 2010.

To find the percentage increase in the adult population:

Since the child population increased by the same percentage, we then:

Therefore, there were 150 children in the town in 2010.
